 Welcome to Sailor.org's Spreadsheets course, part of our professional development program of study. The courses in this program are designed for adult learners who want targeted skills they can immediately apply in a professional setting. For this course, we'll be using leading software on the market, Microsoft's Excel, and we've geared the learning to those with little or no experience. If you can use email, you can learn Excel. You'll need access to a computer with Excel installed to complete this course, but the software is affordable and included in the Microsoft Office package. And Spreadsheets can perform a lot of tasks covered by more expensive and specialized software. One of your first projects will be a simple home budget, but you can also track collections, contacts, birthdays, inventories, and plenty more. In the first unit, you'll learn about rows and columns and how these building blocks come together to make life easier. In the second unit, you'll learn how to enter and manipulate data by recreating a sample spreadsheet for sales tracking. In unit three, you'll use what you've learned to make your very own spreadsheet. Much maligned, off misunderstood, and initially intimidating, spreadsheets are actually pretty easy to learn, really useful, and one of your best friends when it comes to productivity. Let's get started.
